Analysis on the accident casualties influenced by several economic factors based on the traffic-related data in China from 2004 to 2016

Purpose:By studying the economic data related to road traffic accidents in recent 10 years,this paper explores the impact of various economic factors on the number of casualties in traffic accidents in China,and puts forward related prevention and management measures.Methods:Based on five economic factors including the number of new health institutions,health investment,transportation investment and disposable income per capita,this paper collects the data of traffic accidents in 31 provinces and municipalities of China from 2004 to 2016 and estimates the parameters using fixed effect model.Results:The number of health institutions,health investment,transportation investment and disposable income per capita are negatively correlated with the number of traffic accident casualties;the number of new health institutions is positively correlated with the number of traffic accident casualties;health investment and transportation investment have a great impact on the number of road traffic accident casualties.Conclusion:Economic development has a positive impact on improving traffic conditions,but the increase in the number of new health institutions does not reduce the number of casualties in accidents.The irrational layout of health institutions and imperfect road traffic management mechanism should be taken into account.

Road traffic safety:An analysis of the cross-effects of economic,road and population factors

Purpose:Through the study of economic,traffic and population data related to road traffic accidents from 2004 to 2016,this paper analyzed the impact of various factors on road traffic casualties in China,and provided theoretical basis and suggestions for the road traffic safety management in China.Methods:Based on three aspects(economy,road,population)with five factors(gross domestic product(GDP),traffic in vestme nt,new vehicle own ership,new road mileage and newly in creased population),this paper collected the re leva nt data of road traffic accidents in 31 provinces and cities in China,from 2004 to 2016.A panel model was established to carry out empirical analysis.Results:All factors have a significant impact on the number of road traffic accident casualties.When other factors remain unchanged,the number of road traffic casualties decreased by an average of 0.19 for every 100 million CNY increased in GDP.For every 100 million CNY increased in traffic investment,the number of road traffic casualties is reduced by an average of 13.93,indicating that economic development can improve road traffic safety to a certain extent.On the contrary,the growth in road mileage,new motor vehicles and population has increased the number of road traffic casualties.For every 10,000 km of new road mileage,the number of traffic accident casualties has increased by 284.04.For every 10,000 newboms,the number of road traffic casualties increased by 7.33;as the number of new motor vehicles increases by 10,000,the number of road traffic casualties increased by an average of 21.77.Conclusion:The increase of GDP and traffic investment can significantly reduce the number of road traffic casualties in China,which shows that economic development is essential to improve road traffic safety.The numbers of new road mileage,newly increased population and the new motor vehicles are positively correlated with the number of traffic accident casualties in traffic accidents,which reflects the existing problems in road design,distribution of road resources,and traffic management in China.Therefore,it is necessary to improve the economic and road related aspects to improve road traffic safety.

A study of the impact of traffic investment on traffic fatalities in China,2004-2020

Purpose:Road traffic injuries(RTIs)have been one of the most serious public health problems in China.The purpose of this study was to investigate the extent to which traffic investment affects traffic fatalities in China as well as regional differences.Methods:The cohort study analyzed the correlation between traffic investment and traffic fatalities,incorporating additional factors such as economic conditions,road infrastructure,population density,and lighting.The selected variables included the number of traffic fatalities,traffic investment,urban per capita road area,urban road length,road mileage,urban road lighting,population size,and per capita gross domestic product.Relevant data between 2004 and 2020 were collected for an analysis using a fixed effect regression model.Ap<0.05 is considered statistically significant.To reduce the heterogeneity caused by regional differences,the provinces were divided into 6 groups according to administrative districts,and the clustering standard error analysis was carried out.Results:Overall,there has been a significant improvement in road safety in China from 2004 to 2020,but some regions show an increase in traffic fatalities.The model reveals that traffic investment is significantly and positively correlated with the number of traffic fatalities.Holding all other factors constant,each 10,000 yuan increase in transport investment was associated with an average increase of 0.22 road traffic fatalities.In the analysis of regional differences,there was a significant positive correlation between traffic investment and traffic fatalities in the Northwest region and an increase of 10,000 yuan leads to an increase of 0.47.There was a significant negative correlation between road mileage,urban road lighting system,and population and traffic fatalities.For example,holding other factors constant,a 10,000 km reduction in road length would increase the number of traffic deaths by 45.56.The model results of urban per capita road area,urban road length,per capita gross domestic product,and the explained variables showed thatp>0.100,which was not statistically significant.Conclusions:Therefore,traffic investments are essential for governments to develop measures to enhance road safety and reduce the risk of road fatalities.Adjusting traffic road investment and other covariates is conducive to improving traffic safety and reducing the risk of road fatalities.The road safety situation in different regions of China varies greatly.Local governments should consider the actual conditions to provide better road safety configuration policies.
